LD2060-A N-SF11 Bi-Concave Lens; Dia:12.7 mm; f=-15.0 mm ARC 350-700nm
The LD2060-A is a high-quality bi-concave lens offered by Thorlabs, a leading vendor in the optical industry. This lens, designed with a spherical shape, is ideal for applications that require a negative focal length. The lens is made from n-SF11 Schott glass, a material known for its excellent optical properties.
The LD2060-A has a diameter of 12.7 mm and a thickness of 4.7 mm at the edge, tapering down to 3 mm at the center. It boasts an effective focal length (EFL) of -15 mm, making it a powerful tool for focusing or diverging light beams. The lens's front and back surfaces are coated with ARC 350-700nm, a coating that enhances its performance in the visible light spectrum.
This lens is designed to work optimally at a wavelength of 587.6 nm, a standard for many optical applications. Its base shape is circular, ensuring uniformity in light transmission. The lens's inner and outer radii are 0, indicating a symmetrical design that contributes to its high-performance capabilities.
